What is the difference between photovoltaic power station and solar thermal power station?
Solar thermal power is a technology that converts light energy into heat energy and then generates electricity by doing work through a conventional thermal cycle.Solar thermal power is a technology that converts light energy into heat energy and then generates electricity by doing work through a conventional thermal cycle.Solar thermal power produces the same alternating current as conventional thermal power, which is more compatible with conventional power generation and the existing grid and can be directly connected to the Internet.
Solar photovoltaic power generation is the use of solar cell technology, there are photons to make electronic transition, the formation of potential difference, light energy directly into electricity, direct current generation.
The most important difference between the two is in the way they store energy.Energy storage is of great significance to make up for the intermittence of solar power generation and the peak-regulating capacity of power grid.Photovoltaic power generation is directly converted from light energy to electricity, so its excess energy can only be stored in batteries, which is much more technically difficult and expensive than solar photovoltaic power generation, where only heat storage is needed.Therefore, it is easy to store the excess energy to achieve continuous and stable power generation and peak-regulating power generation, which is the most important and obvious advantage of solar thermal power generation over photovoltaic power generation.
Solar thermal and solar photovoltaic power generation have their advantages and disadvantages and have their own application fields.Solar thermal power generation scale is relatively large, while photovoltaic is relatively small, suitable for households, residential areas, etc., including the combination with buildings, therefore, the application scope of the two is not exactly the same.
Solar thermal power generation is mainly used for centralized power generation, while solar photovoltaic power generation is mainly used for distributed power generation.
Solar thermal and solar photovoltaic have their own advantages and development prospects, there is no direct conflict between them.In places where the development of solar power generation is relatively good, there should be both photothermal power generation system and photovoltaic power generation system, so the two are complementary in the long run.In the future, both of them will play a role in the future world energy consumption pattern.The result is the same alternating current as conventional thermal power, which is more compatible with conventional power generation and the existing grid and can be accessed directly.
